Kepler/K2 Quality Control
Automated quality control of Kepler/K2 data products.
This tool allows the Guest Observer Office of NASA's Kepler/K2 Missions to perform a quick sanity check of its public data sets.
In particular, this tool verifies that Target Pixel Files are well-formatted and contain sensible data. It does not replace the pipeline's existing suite of unit tests, it merely provides an independent sanity check on the final data products that the pipeline creates. It is intended to be run prior to each data release and catch obvious errors such as corrupt files or nonsensical data.
git clone https://github.com/KeplerGO/k2-quality-control.git cd k2-quality-control python setup.py install
Once installed, the package adds the
k2qc command-line tool
which can be used to verify a directory of TPF files. For example:
$ k2qc /path/to/tpf-files/ Found 0 issues (234 files checked).
--help for more info:
$ k2qc --help Usage: k2qc [OPTIONS] PATH Check Kepler/K2 data for errors. PATH must be the location of a Kepler/K2 Target Pixel File, or a directory containing such Target Pixel Files. Options: --help Show this message and exit.
One can also redirect the standard output to a text file, e.g.:
$ k2qc /path/to/tpf-files > foo.txt
The package also installs the following auxillary tools to help inspect the contents of target pixel files:
$ k2qc-flags --help Usage: k2qc-flags [OPTIONS] PATH Show a summary of the QUALITY flags. Options: --plot --help Show this message and exit.
$ k2qc-flux --help Usage: k2qc-flux [OPTIONS] PATH Plots the FLUX, FLUX_BKG, and RAW_CNTS time series given a Target Pixel File. Options: --help Show this message and exit.
